in one of the games one of the casters also said there wasn't really anyone for naix to do "naix bombs" with, when nature's prophet (one of the best heroes to do naix bombs with because of the global TP) was on the same team as naix.. yeah... lol

worst casters ive ever heard in any tournament.. and i usually dont hate on casters at all, i like tobi, and all the rest of the casters.. but those guys are just terrible

i think you misunderstand. Sure furion and naix is really good for ganking, but it's really not a good combo for 5v5 teamfighting. What he probably meant, was a hero who naix can infest who can dive into the middle of the fight so that naix who's biggest weakness is his mobility can get right into the middle of everything right away. So, Storm spirit or any blink initiation hero, or some stealth hero's etc... If furion tries to bring naix into the middle of the fight he's gonnna have a bad time.
